Grady, I read some of your posts and I still have some concerns with clearance. Here's what I got.

I was using pieces of solder and I was concerned they were moving so I used a single piece 98mm long across the full width of the piston. I got 0.025" on one side and 0.032" on the other in the squish area. I've never run tighter than 0.026" on my YZ125 so this has me concerned. My thought as this point is to machine 0.005" or 0.010" at a 5 degree angle off the top corner of piston. Thoughts?
